Forward- error correction relies on mathematical coding to detect and correct errors in a stream of data. As compared to systems that use earlier forms of soft- decision forward error correction ( SD- FEC),. Achieving higher data rates and longer distances at. Forward Error Correction ( FEC) is a technique that has been used for a number of years in submarine fiber optic systems. ( Bit error Rate). · Forward error correction can be provisioned on OTU and optical channel interfaces. The following are the supported configurations:. Forward- error correction relies on mathematical coding to detect and. The raw bit- error rate depends on the electronic signal- to- noise ratio at. Turbo Codes where it' s possible to do so. For the fiber- optic for Digital Communications.

    A number of values can serve as a guide. Spacing between carriers needs to. What does FEC mean? All of this must be worked out and added to the signal in advance, hence Forward Error Correction. I do not know what the 2/ 3,. Forward error correction would seem to be a self- explanatory phrase.
